DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 273,051, dated February 27, 1883.

Application fileddannary 15, 1883. (No model.)

To all whom it may concern:

Beit known thatl, LAURENCE FITZSIMMONS, a citizen of the United States, and a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and valuable Improvement in DumpingGars; and I do hereby declare that the following is 4 a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a side elevation ofmyiinproved dumping-car. Fig. 2 is an end elevation of the same. Fig. 3 is a plan View. Fig. 4.- is a vertical cross-sectional view; and Fig. 5 is a detail view, showing the stirrupfastening. I

This invention has relation to side duin pingcars; and it consists in the construction and novel arrangement otthe parts of the framing, and the combination therewith oftheinclined chute boards, the pivoted inclined bottom boards, and their operating devices, all as hereinafter set forth, and particularly pointed out in the claims appended.

In the accompanying drawings, thelctter A designates the longitudinal side sills of the car-frame, the upper surfaces of which are beveled outwardly, as indicated at a.

B designates the end sills, which are cut away, as shown, in their lower faces for the introduction of the drawheads of'the car.

These end sills rest upon blocks m, interposed between them and the side sills, A, and the end and side sills and the blocks m are bound are mortised in the end sills, and are braced transversely by the cross-bars G and longitudinally by the side beams, H, and cap-bars K. The end boards of the car arenailed to the cross-bars G, as indicated at L.

X represents cross-braces, which are arranged in series throughout the length of the car. Each cross-brace consists of two oblique bars, 0 and cl, halved together or otherwise firmly connected at the point ofcrossing. The bars 0 and d respectively extend from the side sills, A, obliquely across the frame to the side beams, H, and are firmly connected to said sills and beams. Upon the upper inclined arms of the cross-braces are laid the outer inclined portions, N, of the bottom flooring, intervals 6 being left between said portions N and the middle beam, E, forming dischargeopenings, which are closed, when the car is to be loaded, by means of the pivoted bottom sections, P, which are connected by longitudinal pivot-rods g, secured to bearings on the outside of the upper arms of the cross-braces. When these vibratory bottom sections are drawn inward and upward by means ofchains h and winding-rollers it, they abut against the inclined lower surfaces of the upper arms of the cross-bar X and their lower edges come together, notches n being provided to permit said edges to pass the cross-braces. In this manner the bottom is completed and supported not only by the cross-braces, but by the center beam, E, which supports said cross-braces.

The side walls are indicated at S. They are secured to the cap-bars and to the upper edge of the stationary floor-sections N, their lower edges being further supported in position by the upwardly-inclined outer portions or extensions, i, of the upper arms of the cross-braces. Vertical braces I support said arms from the side sills, and upon the extensions 2' are located bearings for the longitudinal winding-rollers k. The ends of the winding-rollers are provided with ratchets r, and pawls are pivoted to the car-frame to engage said ratchets when the chains are wound up, serving to hold the pivotedbottom doors or floor-sections, 1?, closed. The ends of each winding-roller should be squared to receive a crank-handle, m.

Ghuteboards Z are secured between the lower arms of the cross-braces, their lower edges resting on the inclined upper edges of the side sills and their upper edges on the center beam, or on the intermediate beams adjacent thereto. These chute-boards are therefore laterally inclined outward, the degree of 2 aaaosii inclination on each side being very nearly that of the pivoted bottom door of the opposite side when the latter is in closed position, so that when one door only is opened the contents will be freely discharged from the surface of the closed door over the chute-board on the opposite side.

This car can be discharged at either side or at both sides, according to requirement.

The construction of the frame is designed to give it great strength, the interlocking ribframes or cross-braces serving to distribute the pressure of the load, and as the bottom doors are chained to the winding-rollers on the outside of the side walls of the grain-chamber the weight on said bottom doors serves to brace the sides of the car.

The car is made as low possible by laying the side sills below the end sills and below the bolsters. The side sills and end sills are to be tied together and braced by wroughtiron stirrup-connections and bolts.

The bottom of the car should also be braced up by means of transverse truss-rods passing over the central beams, and by longitudinal tie-rods. The doors P may be made full length, or may be made in sections, and may open either from the top or from the bottom. When the doors drop in sections from the top, or the full-length door, both sides are hinged to a rod-the same rod-lying in the crotch or fork formed by the ribs crossing each other.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. A dumping-car frame having the beveled side sills, A, and square end sills, B, supported thereon, corner-posts F, cap-bars K, and side beams, H, central beams, and cross-braces X, centrally locked together and bearing against the side sills and side beams, the inclined floorsections N, resting on the upper arms of the cross-braces, and the inclined chute-boards Z, secured to the beveled sills and center beams, substantially as specified.

2. The combination, with the cross-braced car-frame, its inclined floor-sections N, center beams, E, side sills, A, and inclined chuteboards Z, resting on said center beams and side sills, ot' the pivoted bottom doors, P, longitudinally-winding rollers 76 on the outside of the side walls, the ratchets and pawls, and the chains h, connecting the bottom doors to said winding-rolls, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

LAURENCE FITZSI MMONS.
